RING-SPINNING FRAME.

S ECIFICATION forming part of Letters Patent No. 501,427, dated July 11 1893.

Application filed March 27, 1893. Serial No. 467,846. (No model.)

Be it known that I, CHARLES C. KENT, of Taunton, county of Bristol, State of Massachusetts, have invented an Improvement in Ring-Spinning Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In ring spinning frames as now commonly made, the yarn as it is spun is usually wound upon a bobbin without heads, such bobbins containing but a comparatively small quantity of yarn, and consequently the bobbins have to be doffed frequently from the spindles, the doffing being done by children, every mill employing quite a number. Yarns spun on bobbins, as Well as those spun on bare spindles, or cops thereon, have in subsequent processes to be re-wound on spools. In my experiments, I have discovered that by applying to a ring frame two rings, so that both of them may be used in connection with each yarn mass, one for winding, say, the first half, and the other for winding the second half, yarn may be readily spun directly on aspool, such yarn being adapted for warps, a spool containing, as is well understood, a much greater quantity in length of yarn than a bobbin.

My invention therefore consists in a spinning frame containing the following instrumentalities, viz: a series of spindles, aseries of commencing rings concentric with said spindles; and a series of finishing rings, and carrier therefor, said commencing rings being of less diameter than the finishing rings, the carrier for the commencing rings, when the latter are being used to wind the first half of the spool, occupying a position within the finishing ring, substantially as will be hereinafter more fully described.

Figure 1 in elevation and partial section shows a sufficient portion of a ring spinning frame with my improvements added thereto to enable my invention to be understood. Fig. 2 is a like section showing the parts in a different position, as when the first half of the spool is being wound. Fig. 3 is an enlarged sectional detail of the spool. Fig. i is a section through one of the auxiliary heads of the spool; Fig. 5. a sectional detail showing one of the flanges detached, and Figs. 6 and 7, a modification as to the form of the lower head and its connection with a modified form of flange.

On the ring railI mountin usual mannera series of rings a which I shall designate as the finishing'jrings, the drawings showing, howeverbut one of said rings, they being concentric with the spindles, said'finishing rings having each a suitable traveler a. C0- operating with the ring rail having the finishing rings referred to, is a series of commencing rings 0 mounted in a suitable carrier 1), represented in this embodiment of my invention as hinged or pivoted at e to the main ring rail, each commencing ring preferably having an independent carrier. The carrier 12 will in practice be so shaped that, when turned into operative position, as in Fig. 2, to commence the winding of the spool, it will enter the space bounded by the finishing ring a, it being understood that the commencing ring 0 will be used until the spool has been about half filled when it will be turned outwardly into the position shown in Fig. 1.

Referring to Fig. 3, it Will be seen that the spool is composed of a barrel or body f having small flanges g, preferably of metal, each flange having a neck as g'provided with some sort of bayonet slot as 3. When the commencing ring 0 is in use, see Fig. 2, the'smaller flanges only are carried by the barrel. When the spool has been about half filled, as in Fig. 2, it will be removed from the spindle and the auxiliary heads h, h, will be applied, said heads having suitable pins h to enter the bayonet slots 3, each neck g having preferably two such slots. While the spool is OK the spindle and the ring rail elevated, the operator will turn the carrier b and commencing ring 0 over into the position shown in Fig. 1, and will then apply the spool with its IOO Fig. 2 shows the spool as being filled, and it will be readily understood that, by the use of the commencing and finishing rings, supported and combined by the ring rail, as specified, either ring may be used readily at will, and a large mass of yarn may be wound upon a spool with but a slight intermission.

This invention is not limited to the exact construction of the rings employed, nor to the exact shape of the carrier for the commencing ring, so long as the said carrier is combined with the frame in such manner as to be readily put into and out of position as the re quirements of the work require.

The lower head of the lower end of the spool may be constructed as shown at m Fig. 6 it being provided with aninner annular groove and with a spring clasp m attached in the central opening of the head so that it may expand into said grooves, the clasp, in this present embodiment of my invention having at one end a prong m to enter a hole in the head. The flange 'n at the lower end of the bobbin body may be of wood and have an eX ternal annular groove n.

In practice, to apply the lower head m, I pass it over the upper flange of the bobbin, the thread having been broken, and I pass the said thread down over the flange 'n, which will preferably be beveled or tapered slightly and the clasp expands slightly and then springs into the groove n.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A ring spinning frame containing the following instrumentalities, viz;a series of spindles; a series of commencing rings concentric with said spindles; and an auxiliary series of finishing rings and carriers therefor, said commencing rings being of less diameter than the finishing rings each commencing ring when operative during the spinning and winding of the first part of the yarn load on the spool, occupying a position within the circle bounded by the corresponding finishing ring and concentric to the spindle, substantially as described.
